Title: Method of purifying aqueous dispersions
IPC: C08C1/04
Filed: 1929-03-15
Abstract: 319,344. Anode Rubber Co., Ltd., (Assignees of Newton, E. B.). Sept. 22, 1928, [Convention date]. Emulsions, making.-Aqueous dispersions such as natural or artificial latices of rubber, gutta percha, balata, &c., and emulsions of oils, waxes, asphalt, &c. or suspensions of solids such as zinc oxide, silica, carbon black, sulphur, &c. suitable for use with dispersions of rubber, are treated to remove dissolved gases, volatile substances or gas forming principles, by blowing a neutral gas through heated dispersions. The neutral gas is one which has little effect on the stability of the dispersion and is insoluble in hot water. The invention is particularly applicable for the removal of ammonia or other alkaline base from preserved rubber latex intended for electrodeposition or electrophoretic processes in which absorbed carbon dioxide is liberated and gives rise to pitted or spongy deposits. The heating may be effected by steam coils or jackets and the neutral gas may be steam. Where dilution is not objectionable the steam blown through the dispersion may be used to heat it. The temperature should approach the boiling point of the dispersion. Specification 257,885, [Class 70, Indiarubber &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) mentions washed air as the neutral gas. This subject-matter does not appear in the Specification as accepted.

Filed: 1937-06-15
Abstract: 493,598. Loose-leaf binders. KEENE, J. A. June 15, 1937, No. 8482/38. Divided out of 493,568. [Class 146 (i)] In a loose-leaf binder comprising clamping- bars 3, 4, Fig. 1, to which the covers 26 and a back member 14 are hinged and one of which carries mechanism for locking the ends of filing-pins carried by the other, the bars 3, 4 are formed with open-ended depressions 28 to receive hinge sockets 5, 6 on the covers, hinge pins being threaded through the sockets from the inside of the bars 3, 4. Similar depressions may be provided to receive hinge sockets 15 on the back-member 14. Each bar 3, 4 is formed of approximately D-section of sufficient depth to receive the post-locking mechanism or the post-carrying bar 25. The depressions 28 are formed by cutting slits in the sides of the bars and pressing inwardly the material between the slits. They also serve to secure the bar 25 in place. Cover plates 1, 2 carrying the covers 26 and integral with the sockets 5, 6 are bent inwardly at 13 so that the cover can be opened to the position shown at 27. Plugs of rubber, artificial resin, or fibre may be inserted in the open ends of the bars 3, 4 to prevent damage to table surfaces when the binder is placed thereon. The back 14 has a strip 19, Fig. 5, of flexible material disposed between strengthening ridges 22 thereon and secured by members 36 with tongues 24 threaded through slots 23 in the strip 19 and back 14. A further strip 20 of an ornamental character or imprinted with letters may be secured by adhesive to the strip 19. The members 36 may be replaced by a single member extending the length of the back and the strips 19, 20 may be replaced by a strip of stiff cardboard covered with leather. Specification 493,568 is referred to.

Abstract: 766,102. Spindle drive. SPINNBAU GES. March 24, 1955 [April 2, 1954], No. 8554/55. Class 120 (2). [Also in Group XXIV] A clutch arrangement (see Group XXIV) comprises a worm and a worm gear, one of which is associated with a clutch member and is moved axially for clutch engagement while the worm and worm gear remain in toothed engagement. In one form, a driving shaft 1, Fig. 2, carries a clutch member 2. A driven clutch member is formed by a helically toothed gear 3 axially and rotatably mounted upon the shaft 1. The gear 3 meshes a worm thread formed on a spinning or twisting spindle 5 and is moved axially to engage the driving clutch member 2.

Abstract: The invention comprises phthalocyanine dyestuffs of the formul Pc-(CH2NHCH3)n and Pc-[CH2N(CH3)2]n, where n is an integer from 1 to 8, and Pc is a phthalocyanine residue.  They are made by reacting with formaldehyde in presence of formic acid at a temperature up to about 100 DEG  C. the dyestuff of the parent Specification having the formula Pc-(CH2NH2HX)n, where X is halogen and n is a number from 1 to 8, preferably in the form of their free bases. The formic acid acts in part as solvent and may therefore be in part replaced by other solvents, such as acetic acid.  The products dye cotton and wool reddish-blue shades.  An example describes the treatment of di-o -aminomethyl-copper-phthalocyanine to give di-o -dimethylaminomethyl-copper-phthalocyanine.

Title: New aqueous wax emulsions
IPC: D06M13/02
Filed: 1946-03-21
Abstract: Aqueous wax emulsions comprise a wax, for example paraffin wax, ceresin, beeswax, or spermacetti, or mixtures thereof melting at a temperature not exceeding 90 DEG  C., a modified bovine blood albumen, and a salt of an amphoteric metal, for example, aluminium formate, acetate or sulphate, or zirconium oxychloride or formate. The bovine blood albumen is modified by treatment with aqueous alkali at from 20 DEG  to 60 DEG  C. for at least 2 hours, and then addition of sufficient acid, e.g. formic or acetic, to bring the pH value to below 4.4.  Other substances to improve stability or water-repellency may be incorporated, such as crystal rosin, stearic acid, and the condensation product of b -naphthol with 5 mols. of ethylene oxide. The emulsions may be prepared by emulsifying directly a molten wax in an aqueous solution of the modified blood albumen at a pH value below 4.4 using a homogenising machine.  An aqueous solution of the salt of the amphoteric metal may be added before or after emulsification. Other substances may be added to the emulsion or may be incorporated in the molten wax.  Textiles may be rendered water-repellent by impregnation with the emulsions and subsequently drying.

Title: Improvements relating to the production of polyhydric alcohols
Filed: 1957-03-18
Abstract: Glycerol is among the products when a mixture of hexitols and pentitols, obtained by the hydrogenation of aqueous solutions of wood sugar, is subjected to catalytic hydrogenation in two stages, the first being carried out at a temperature up to 210 DEG  C. and the second at a temperature of 250-300 DEG  C.  Suitable hydrogenation catalysts are Raney nickel and mixed catalysts containing chromic oxide, such as a silver-copper-chromic oxide catalyst.ALSO:Polyhydric alcohols with less than 5 carbon atoms in the chain are produced by subjecting a mixture of hexitols and pentitols, obtained by the hydrogenation of aqueous solutions of wood sugar, to catalytic hydrogenation in two stages, the first being carried out at a temperature up to 210 DEG  C. and the second at a temperature of 250 DEG  to 300 DEG  C.  Suitable hydrogenation catalysts are, for example, Raney nickel and mixed catalysts containing chromic oxide such as a silver-copper-chromic oxide catalyst.  The preferred pressure for carrying out the hydrogenation is 100-200 atm.  In the examples: wood sugar liquors are hydrogenated in the presence of Raney nickel at 60 DEG  C. and 55 atm. and the resulting solution is hydrogenated at 206 DEG  C. in the presence of (a) copper chromite and (b) a silver-copper-chromic oxide catalyst and the resulting mixture is distilled; the residue is then hydrogenated at 260 DEG  C. and the resulting mixture distilled; from the two distillates there are obtained glycerol, propylene glycol and ethylene glycol.

A label (Fig. 1) has an area 1 surrounding an area 2 from which it may be easily detached with the fingers. In the form shown, the two areas are defined by a gap 4 across which are bridging pieces 3 of the material of the label. The two areas could also be defined by scoring, perforations or other means. One side of the label may have a layer of adhesive which may be protected by a readily removable backing layer having separable areas 5 and 6 (Fig. 2, not shown) corresponding with the two areas of the label. Area 1 of the label is adhered to part of the upper face of a collecting box 7 (Fig. 3, not shown), and part of closure member 8 so that it seals the gap 9 (Fig. 4, not shown), formed when the closure member is fixed into the upper face of the collecting box. Area 2 covers a coin slot in the closure member and may be subsequently detached and affixed to another part of the collecting box. The upper face of a collecting box may have an upwardly projecting circular ridge surrounding the label. In another form of the label there may be no backing layer, in which case one surface may be covered with a water-soluble gum or have adhesive applied to it prior to affixing. Using this form, the closure member would have a circular recess to prevent the area 2 of the label sticking to it.
